MAN6640 Equivalent & Substitute Parts

Part Overview

The MAN6640 is a dual-character 7-segment LED display module manufactured by onsemi, featuring orange LEDs in a common cathode configuration. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and production continuity. The display operates at a maximum forward voltage of 2.5V with a test current of 20mA and is housed in an 18-DIP package measuring 0.600" (15.24mm) pitch.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MAN6640 are identified based on the following critical parameters that determine functional compatibility:

• Display Configuration: 2-character, 7-segment, common cathode architecture
• Physical Package: 18-DIP (0.600", 15.24mm) pitch for PCB compatibility
• Digit Size: 0.56" (14.22mm) for form factor equivalence
• Electrical Characteristics: Forward voltage and test current within acceptable operating ranges for existing circuit designs
• Color Specification: Orange or functionally equivalent wavelength for visual consistency

The substitute parts listed below maintain these core parameters while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

DC56-11EWA (Kingbright): This substitute maintains the 18-DIP package, common cathode configuration, and 0.56" digit size. The forward voltage of 2V is lower than the MAN6640's 2.5V maximum, reducing power dissipation in existing circuits. The test current remains at 20mA, ensuring compatibility with standard drive circuits. The part is RoHS3 compliant and carries active product status, providing long-term availability and supply chain stability.

LBP-602DK2 (Rohm Semiconductor): This substitute offers the same 18-DIP package and common cathode architecture. The forward voltage of 1.9V and reduced test current of 10mA result in lower power consumption compared to the MAN6640. The significantly higher millicandela rating (250mcd versus 2.2mcd) provides enhanced brightness. The part is RoHS3 compliant with active product status. The wavelength peak of 605nm represents a shift toward red within the orange spectrum compared to the MAN6640's 630nm.

Both substitutes comply with REACH regulations and carry EAR99 export classification, matching the MAN6640's regulatory profile.

Frequently Asked Questions (FAQ)

Q: Can the DC56-11EWA replace the MAN6640 directly? A: The DC56-11EWA maintains identical package, digit size, and common cathode configuration. The lower forward voltage (2V versus 2.5V) and identical test current (20mA) allow direct substitution in most applications. Circuit validation is necessary if the design relies on specific voltage characteristics.

Q: What is the primary difference between the two substitute options? A: The DC56-11EWA maintains closer electrical parity to the MAN6640 with a 2V forward voltage and 20mA test current. The LBP-602DK2 operates at lower voltage (1.9V) and current (10mA) with significantly higher brightness (250mcd). Selection depends on power budget and brightness requirements of the application.

Q: Are the physical dimensions compatible with the MAN6640 footprint? A: All three parts use the 18-DIP (0.600", 15.24mm) package. Dimensional variations are minimal (within 0.002" to 0.05mm), ensuring PCB compatibility. The 0.56" digit size is consistent across all parts.

Q: Do the substitute parts have the same color output? A: The DC56-11EWA is specified as red (627nm wavelength), while the MAN6640 and LBP-602DK2 are orange. The DC56-11EWA represents a color shift and may not be suitable for applications requiring orange display consistency. The LBP-602DK2 maintains orange color specification with a 605nm wavelength, closer to the MAN6640's 630nm.

Q: What are the compliance and regulatory considerations? A: All three parts carry REACH Unaffected status and EAR99 export classification. The DC56-11EWA and LBP-602DK2 are RoHS3 compliant, while the MAN6640 is obsolete. All parts have MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions.
